clams grows rate

[bullitr]

assuming that the tank is ideas
calcium above 450
alk above 10
lots of fish waste
nitrate below 5
directly under a 400 watts metal halide with lumenach
low/ moderate flow
what is the possible growth rate on
derasa 5"
crocea 3.5"
maxima 3.5"
the only issue they retract about 5 x a day due to my 2 10" naso's passing by and block there lights but it open right away for 3 months the derasa and maxima learn how to adjust to that.
whats is the best growth on clams
derasa
crocea
maxima
squamosa
gigas

 

[a4twenty]

derasa 2" - 3" per year
crocea 1/2" - 1" per year
maxima 1" - 2" per year
squamosa 1 1/2" - 3 1/2" per year
gigas 1 1/2" - 4 3/4" per year

tridacnid clams grow quite fast until they reach sexual maturity, then slow greatly.

[Steven1015]

so do claims grow pretty fast when there only like a inch in size?

 

[a4twenty]

yes but how fast depends on the species and tank conditions as well.

my gigas grew about 2 inches in 3 months.. And my deasa is about a month now and has about and inch in growth. my squamosa when it put on new shell sould do and inch in a few days then again would not grow for a long time befor that.
